Descriptions

The DC Light source lamp with parabola reflector.

The condensor lens leads the light generated from the lamp to the end sur-
face of the light-tunnel through the IR-cut mirror.
The IR-cut mirror is set in this unit to eliminate the excessive heat by the lamp
energy.

This color filter separates the white light into the 3 colors R,G and B.
A photo-sensor should be set in this unit to detect the transition timing pproperly
between color filters.
The maximum rrotating speed is 9000rpm.

This unit leads the illumination spot to effective area on DMD.

This prism also leads the illumination spot to effective area on DMD and at the
same time leads the reflection lights on the DMD to the projection lens.

This chip turns on and off in projection to each color component per dot de-
pending on the input source.

This lens enlarges and projects the incidend light coming from the DMD.

Note: A piece of temporary tape is attached on the focus ring that comes with the replacement projection lens. Keep

this tape in place until the finish of the adjustment.

(1) Provide a distance of 2.4 m between the set and the screen and adjust the zoom knob to “wide end”.
(2) Adjust the lens shift until the projection lens comes to the same level as the center of the screen.
(3) Detach the optical unit top cover A from behind the projection lens.
(4) Loosen the four hex screws B in the back of the projection lens.
(5) Insert the adjustment screwdriver C (9EVDRIVERZ9000) in the hole D at the back of the lens. Put the center of the

screen in the best focus. (Preferably feed the SXGA signal for 1-dot white crosshatch pattern or 1-dot white dot
pattern on black background.)

(6) Tighten the four hex screws B to the torque of 0.3 Nm (3.06 kgfcm), and apply screw loctite to them.
(7) Peel the temporary tape off the focus ring of the projection lens.
(8) Attach the optical unit top cover A back into position. Finally fix the two screws E and apply screw loctite to them.

Make adjustment by the indication territory on the screen to prevent the circumference of the screen from getting
dark because a lighting range deviated.

1. Remove the top body so that the optical unit may be seen. Display white only screen on the screen.
2. Detach the mirror adjustment part cover 

1

 on the bottom right of the projection lens.

3. Turn three screws with special hexagon wrench (9HPH10XL120) and adjust so that a part of the screen may not get

dark because a lighting range deviated.

4. Mount the adjustment part cover

5. Mount the top panel.

Insert hexagon wrench 
in this direction.

Note: DMD chip and Formatter PWB are supplied at the same time, and an exchange only with DMD isn't done.Refer

to "REMOVING OF MAJOR PARTS" when exchanging Formatter PWB.

There is no need to readjust the back focal distance of the projection lens. If focusing is noticeably poor, however,
make this readjustment.

(1) Provide a distance of 2.4 m between the set and the screen.
(2) Adjust the lens shift until the projection lens comes to the same level as the center of the screen.
(3) Detach the optical unit top cover A from behind the projection lens.
(4) Loosen the four hex screws B in the back of the projection lens.
(5) Adjust the zoom knob at the front of the projection lens to “tele end” and ensure good focusing.
(6) Then adjust the zoom knob at the front of the projection lens to “wide end”.
(7) Insert the adjustment screwdriver C (9EVDRIVERZ9000) in the hole D at the back of the lens. Put the center of

the screen in the best focus. (Preferably feed the SXGA signal for 1-dot white crosshatch pattern or 1-dot white
dot pattern on black background.)

(8) Move the zoom knob from “wide end” back to “tele end” and see if focusing is ensured. If not, repeat the above

steps (5), (6) and (7) until the best focus is achieved.

(9) Tighten the four hex screws B to the torque of 0.3 Nm (3.06 kgfcm), and apply screw loctite to them.
(10) Attach the optical unit top cover A back into position. Finally fix the two screws E and apply screw loctite to them.

mand because otherwise the PC board itself will be
initialized.
(The delivered PC board has been factory-adjusted.)
If by any chance the PC board must be readjusted,
follow the instructions in "Adjusting the PC Board"
on page 28.
